Pd-catalyzed cyclizations of 1,n-allenynecarboxylates have been found to exhibit three different cyclization modes: cycloreduction, arylative cyclization, and [2+2] cycloaddition depending on the reaction conditions.

A palladium [2 + 2] cycloaddition of 1,6- and 1,7-allenyne carboxylates and microwave-mediated [2 + 2] cycloaddition of various 1,n-allenynes were developed and, particularly, the microwave irradiated [2 + 2] cycloaddition of allenynes can provide a simple, general and eco-friendly synthetic method to fused bicyclo[m,2,0]alkadienes.
